TP-Link TL-MR10UをOpenWRT化する

TP-Link TL-MR10UをOpenWRT化します。
おそらく現時点では戻せないと思われるので、後悔しない方以外は諦めてください。(tftpでの復旧が可能か不明です。)

ちなみに純正ファームではこんな感じのインタフェースになっています。
中国語しかありません。(英語すら選べないようです。)


OpenWRTのイメージは、本家のtrunkから取得することになります。
http://wiki.openwrt.org/toh/tp-link/tl-mr10u
まだまだ安定版は先と思われるので、自分でビルドするつもりで居た方が良さそうです。(バイナリもダウンロードは可能です)

ダウンロードできるopenwrt-ar71xx-generic-tl-mr10u-v1-squashfs-factory.binは、WebインタフェースからOpenWRT化可能なイメージになります。
tftp用は用意されていないので、まだ仕様が明らかになっていないと思われます。

では、OpenWRT化の手順ですが、管理画面のメニューから系统工具、软件升级と選択する。
リンク先は、http://192.168.1.1/userRpm/SoftwareUpgradeRpm.htm となっている筈です。


あとは入手しておいたファームウェアのイメージを選択し、升级を押すだけです。
再起動後は、OpenWRTが起動する訳ですが、有線Ethernetがlanとして割り当てられDHCPサーバが稼動しています。
無線インタフェースは無効化されている為、有線で接続する必要があります。

BuffaloなどOpenWRT化と異なり、このイメージにはWeb管理画面は導入されていない為、telnetで入るしか操作する方法はありません。
設定ファイルを直接いじるしか設定を変える方法が無いので、OpenWRTのマニュアルを事前に用意しておくと便利でしょう。

ちなみにFlashの空き容量は期待しない方が吉。
メモリも小さいので幻滅しない様、小型のOpenWRT機が入手できるぐらいの気持ちに留めた方が精神的ダメージは少ないです。

せっかくなので起動時のログを貼り付けて起きます。
